# The NASA Authorization Act 2026 overlap mandate is the first policy-engineered mandatory Gate 2 mechanism for commercial space station formation

The NASA Authorization Act of 2026 includes an overlap mandate: ISS cannot deorbit until a commercial station achieves concurrent crewed operations for 180 days. This is the policy-layer equivalent of 'you cannot retire government capability until private capability is demonstrated'—a mandatory transition condition encoded in legislation.

This represents the first policy-engineered mandatory Gate 2 mechanism for commercial space infrastructure. Unlike voluntary commercial development or market-driven transitions, the overlap mandate creates:

(1) Binding legislative prerequisite—ISS retirement is contingent on commercial capability demonstration, not aspirational timeline or budget pressure;

(2) Economically activating government anchor tenant relationship—the qualifying commercial station gains de facto government customer status through the transition dependency, reducing private capital risk;

(3) External enforcement through Congressional authority—not self-certification or voluntary pledge, but legislative mandate with appropriations control;

(4) Specific performance threshold—180-day concurrent operations is measurable, verifiable, and creates clear success criteria.

This contrasts with CCtCap and CRS, which were mandatory development programs but did not include explicit overlap requirements as legislative prerequisites for government capability retirement. The overlap mandate extends the mandatory instrument pattern to include transition sequencing, not just capability development.

If enacted as written, this creates the strongest coordination mechanism yet for commercial space station formation—stronger than CLD alone (which is commercial development funding without retirement contingency) because it makes government capability retirement dependent on commercial capability demonstration.
